“…The results for the Fourth Colony agree with this observation, because 42 families of insects were collected, representing 95% of the sampled communities. The same pattern, with a high abundance of Insecta, was also observed in other studies in southeastern and central-western Brazil, such as in Uieda & Gajardo (1996), Kikuchi & Uieda (1998), Serrano et al (1998), Bueno et al (2003) and Ribeiro & Uieda (2005).…”

“…Nevertheless, few studies have inventoried the aquatic invertebrates of inland watercourses in southern Brazil. In the state of Rio Grande do Sul (RS), two such studies have been done, one in the Sinos River Basin (Stenert et al 2002) and the other in Taquara and Tainhas brooks, in the municipal districts of Taquara and São Francisco de Paula, respectively (Bueno et al 2003), both in the northeastern part of the state. It is important to cite the pioneering work developed by Kleerekoper (1990), which was the study of lotic environments of the littoral region of the Rio Grande do Sul.…”

Diversity and abundance of the benthic macrofauna in lotic environments from the central region of Rio Grande do Sul state, Brazil

Ayres-Peres, L., Sokolowicz, C.C. The benthic fauna plays an important role in the trophic web and the nutrient flow of limnetic environments. This work aimed to study the diversity and abundance of the benthic invertebrates in four watercourses in the central region of the state of Rio Grande do Sul, Brazil. Sampling was done seasonally at each site, with a long-handled net at the margins (banks) and streambed, from November 2001 through September 2002. Margalef richness, Shannon diversity and Pielou evenness indices were applied to the data analysis. A total of 58 families and three other major taxa (Hirudinea, Oligochaeta and Copepoda) of invertebrates were identified. The highest values of diversity and abundance were recorded at the margins of the rivers, in the same pattern found in other tropical and subtropical regions. This is the first inventory of benthic invertebrates from central region of Rio Grande do Sul, which will be important for future studies of the diversity and conservation of this fauna, because human alterations of the environment have already begun.

“…The lower frequency of organisms at Point 2 could be related to the loss of riverbank vegetation and its replacement by shrubby, exotic vegetation, and to a lower availability of heterogeneous substrates (mostly sand), as noted by Bueno et al (2003).…”

“…Ephemeroptera are adapted to hard substrates and are not frequent in sandy substrates, which may affect the index's results. Bueno et al (2003) noted that sandy substrates can limit the distributions of species, since they lack hiding places and have low food availability. Future comparisons of these indices may benefit from comparing only sites with similar substrates.…”

MENEZES, M.S. A comparative analysis of biotic indices that use macroinvertebrates to assess water quality in a coastal river of Paraná state, southern Brazil. Biota Neotrop. 11(4): http://www. biotaneotropica.org.br/v11n4/en/abstract?article+bn00411042011.Abstract: Biotic indices to monitor water quality are helpful tools for evaluating the health of rivers and lakes. In Brazil water samples are mainly analyzed using physical and chemical attributes, because most biotic indices were developed in other countries and their effective application to Brazilian ecosystems requires significant research. This study compared four biotic indices commonly used to evaluate water quality via benthic macroinvertebrates in order to determine which index best reflects ecosystem health in a coastal river in Brazil's Paraná state. We also analyzed functional feeding groups. The indices studied were: 1) EPT (percent of Ephemeroptera, Plecoptera and Trichoptera); 2) BMWP' (Biological Monitoring Work Party System); 3) BMWP'-ASPT (Average Score per Taxon); and 4) HFBI (Hilsenhoff Family Biotic Index). All indices were calculated from five samples collected from April 2005 to April 2006 at two stations on the coastal do Pinto River. The river's headwaters are inside a protected area but impacts increase downriver (e.g., towns, cattle grazing, tourism). The HFBI index did the poorest job of reflecting water quality. No one index performed better than the others, and all indices yielded water quality scores that did not accurately reflect macroinvertebrate community structure because all of them had differences between ordination scores and the structure of assemblage. The functional feeding groups protocol classified the lower stretch of the river as disturbed due to human impacts, suggesting that this method is a good one to evaluate health in environments.

“…However, the diversity and ecology of elmids in Rio Grande do Sul remains poorly known (Hinton 1972, Benetti et al 1998, Salvarrey 2011. In general, the spatial distribution of these beetles has been registered especially at family level, in studies of freshwater macroinvertebrates (e.g., Wiedenbrug et al 1997, Bueno et al 2003, Pereira & De Luca 2003. The occurrence of 14 genera in Santa Catarina state (Segura et al 2013) and of 19 genera in Argentina (Archangelsky & Manzo 2006) suggests that the diversity of elmids genera in Rio Grande do Sul could be greater than it is known so far.…”

Diversity and distribution of riffle beetle assemblages (Coleoptera, Elmidae) in montane rivers of Southern Brazil

., SPIES, M.R., PIRES, M.M. Diversity and distribution of riffle beetle assemblages (Coleoptera, Elmidae) in montane rivers of Southern Brazil. Biota http://dx.doi.org/10.1590/1676-060320140615183046Abstract: The diversity and spatio-temporal distribution of Elmidae (Coleoptera) assemblages in montane rivers and streams of southernmost Brazil (Rio Grande do Sul state) were studied. Six genera were found, represented mostly by larval specimens. Austrolimnius and Macrelmis are new occurrences in the region. Assemblages' genera composition and dominance were related to the presence of the macrophyte Podostemum. Also, water temperature and stream depth and velocity were the most important drivers related to the assemblages' distribution. Richness and abundance were positively related to high water velocity and negatively to stream depth. Temporal patterns were detected especially in assemblage abundance, yet a slight pattern in richness was also observed. The seasonal structure was related to warm temperatures, but temporal distribution of Elmidae assemblages appears to be related to the dominant genera life cycles. The studied area shows an overall Elmidae richness similar to that found in some tropical areas and the role of mountainous environments in sustaining high rates of regional diversity in the Neotropics is stated. Keywords: aquatic insects, streams, Neotropical region.
